What Does Infrared (IR) Mean?
Infrared (IR) is a wireless mobile technology used for device communication over short ranges. IR communication has major limitations because it requires line-of-sight, has a short transmission range and is unable to penetrate walls. IR transceivers are quite cheap and serve as short-range communication solutions.
Techopedia Explains Infrared (IR)
IR-enabled devices are known as IrDA devices because they conform to standards set by the Infrared Data Association (IrDA). IR light-emitting diodes (LED) are used to transmit IR signals, which pass through a lens and focus into a beam of IR data. The beam source is rapidly switched on and off for data encoding.
